Subject: [PATCH v4 0/3] omap3 nand: cleanup exiting platform related code
Date: Thu, 27 May 2010 18:54:04 +0530 [thread overview]
Message-ID: <1274966647-32500-1-git-send-email-s-ghorai@ti.com> (raw)
In-Reply-To: <Sukumar Ghorai <s-ghorai@ti.com>
The following set of patches applies on top of for-next branch.
http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git
Patches verified on: omap3430-SDP, omap3630-sdp, zoom3 and beagle board
And these are the patches required to address the following input -
1. The NAND driver needs to stop tinkering with the GPMC registers
The omap General Purpose Memory Controller (GPMC) registers are omap
specific, and not driver specific. Tinkering with these registers can
cause issues with the other devices on the GPMC.
2. Passing hardcoded GPMC_CS0_BASE needs to go from the board files
Passing hardcoded GPMC virtual addressess is sure way to mess up things.
This should all become unnecessary once the NAND drivers stops messing
with the GPMC registers directly.
Discussion: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg27630.html
v3: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg28715.html
Functions related to ecc and prefetch engine are optimized.
v2: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg28467.html
Few functionality was missing like - There should be some locking
as only one chipselect can use the ECC or prefetch engine at a time.
If you have NAND in two chipselects, bad things would happen.
v1: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg28164.html
Additionally, it was needed to implement more functions for the
platform init code to use.
